Ardnakinna Lighthouse, Co. Cork

Ardnakinna is simultaneously one of the youngest and oldest lighthouses around the coast. The tower was originally constructed in 1850 as an unlit beacon, and was then converted to a full lighthouse by adding an ex-lightship lantern in 1965.
Seen here from the Irish Lights helicopter while returning from a visit to the Fastnet, the mouth of Bere Haven harbour is on the left and Castletownbere itself is in the background.
